Abstract

The main cause of solar facility fires is arc, and in the last 3 years ('16 to '18), about 80% of domestic solar facility fires have been caused by arcs. The capacity of solar power facilities installed around the world continues to increase, and fires caused by arcs are also expected to increase as the solar power generation facilities that were initially installed become obsolete, In this paper, an arc generation test was conducted based on the UL1699B test standard. As a result of the test, the arc generation satisfied the minimum arc current according to the test conditions, and DC arc characteristics were analyzed through data such as arc voltage and arc current according to variables such as speed of moving electrodes and electrode spacing.
